Dahlia plant named ‘DAENOGTYVE’

ABSTRACT

A new distinct cultivar of  Dahlia  plant named ‘DAENOGTYVE’, characterized by its upright to slightly spreading shape, with stiff and strong lateral stems and thick compound leaves, with up to 12 leaflets. The color of the mature leaves are RHS Yellow-green 147A (upper side) and RHS Grayed-green 191A (Underside). Compound leaves are 8-24 cm in length, and 8-18 cm in width. Only a few single leaves peduncle are present. Composite flower heads are 10-12 cm in diameter, with a large number of ray florets (about 150 to 200). The ray florets are white near base to RHS Red-purple N74A. The amount of white on the ray floret differs from 20%-50% (a few even 80%).

Latin name of the genus and species of the claimed plant: Dahlia Cav.

Variety denomination: ‘DAENOGTYVE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia Cav., of the Compositae (Asteraceae) family, hereinafter referred to by the cultivar name ‘DAENOGTYVE’.

The new Dahlia cultivar is a product of a planned breeding program conducted by the inventor, Rune Nielsen, in Stige, Denmark. The objective of the breeding program is to develop a new Dahlia cultivar with an upright, strong and healthy growth habit, suitable for large scale container production and with good garden performance; fully double flowers creating globular-shaped flower head (composite flower heads with many ray florets) with an attractive inflorescence color.

The new Dahlia cultivar originated from a cross, made in a controlled breeding program by the inventor in 2008, in Stige, Denmark. The female or seed parent is a Red-purple Dahlia designated 5876G (Breeder's Reference; unpatented). The male or pollen parent is a light Purple-violet Dahlia designated 5187C (Breeder's Reference; unpatented).

Asexual reproduction of the new Dahlia cultivar by terminal cuttings was first performed in September, 2009 in Stige, Denmark, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘DAENOGTYVE’, which in combination distinguish this Dahlia as a new and distinct cultivar:

-   -   1. Cultivar, with upright to slightly spreading shape;     -   2. Cultivar with stiff and strong lateral stems and thick         compound leaves, with up to 9 leaflets. Color of mature leaves         RHS 147A (upper side) RHS 191A (Underside);     -   3. Compound leaves with 2 to 12 leaflets, 8-24 cm in length, and         8-18 cm in width, with only a few single leaves present near         peduncle;     -   4. Composite flower heads, 10-12 cm in diameter, with a large         number of ray florets (about 150 to 200); and     -   5. Ray floretsare white near base to RHS Red-purple N74A; the         amount of white on the ray florets differs from 20%-50% (a few         even 80%).

Plants of the new Dahlia ‘DAENOGTYVE’ differ from plants of the parent, in the traits described in Table 1.

(The male and female parents are no longer available for a detailed evaluation. The evaluation is therefore based on historical data)

DETAILED BOTANICAL DESCRIPTION

The new Dahlia ‘DAENOGTYVE’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Dahlia ‘DAENOGTYVE’ as grown in a protected environment in a glass, greenhouse in Fyn, Odense, Denmark, under conditions which closely approximate those generally used in commercial practice. During propagation, conducted in a glasshouse, vegetative cuttings were planted 6 Jul. 2011 in small propagation pots with peat as substrate, and then placed in a plastic tunnel averaging about 21° C. and received photoperiodic treatments of 18 hours. Supplementary light was given when natural light fell below 3000-4000 Lux. Rooting occurred about 12 days after planting. In third week after planting the cutting (27 Jul. 2011), young plants were potted in an 19 cm pot in a glass covered greenhouse, maintained at 18° C. to 26° C. during the day, and at 17° C. to 19° C. during the night. Plants were grown under natural daylight conditions. Irrigation was done with water. The EC measured in the soil was maintained between 2.0 to 3.0. One week after potting, the first growth regulation was given: a spray with 85% daminozide, 0.2%, 40-100 m1/m2. During the production time, 9 additional sprayings were given with 85% daminozide, 0.2%, 40-100 m1/m2.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under September daylight conditions at approximately 12:00 PM and 2:00 PM in Fyn, Odense, Denmark. The age of the ‘DAENOGTYVE’ plants described is 10-11 weeks (including propagation time).
